TO ALL WHOM IT MAY CONCERN:

Be it known that I, GEORGE B. BRAYTON, of Providence, in the county ofProvidence, and State of Rhode Island, have invented certain new anduseful Improvements in Eyelets; and I do hereby declare that thefollowing specification is a full, clear, and exact description thereof.

Eyelets haye heretofore been manufactured of a composition metalcomposed mainly of copper. The process of forming such metal intoeyelets by means of dies renders it so dense and unyielding that theeyelets require to be annealed before they are fit for use. Again, it isneeessaryto clectro-plate or by other means silver" the eyelets beforethey are suitable for market, and this operation involves the necessityof drying in a bath of heated saw-dust and much incidental manipulation.

It is also true that no one of the various machines which have beenconstructed for manufacturing eyelets have been practically successful,forthe reason that no dies and formers can be made for any continuedperiod to withstand the strain brought upon them in working metal likethat heretofore employed with the rapidity requisite to make eyelets inquantities to be profitable.

I propose to manufacture eyelets from metal of a peculiar character,which shall not become dense and L unyielding as the efl'ect of beingworked, and which shall possess in itself sufficient lustre to renderunnecessary any operation of electro-plating.

I make use of a metal for this purpose which is composed oftin and zincin combination. The proportions 7 which I have found to be the best arefour parts of the former to one part of the latter. These metals do notincline to union, and to insure the composition being homogeneous it isnecessary, after both metals have been reduced to the point of fusion inthe same crucible, to agitate the mass by stirring until a completeamalgamation of the particles ensues. The proportion of zinc may beincreased if desired, but care should be taken that it is not insufficient quantity to render the composition brittle. After tlie masshas become sufficiently united it is to be cast in moulds into the formof ingots, which are to be rolled into sheets of the proper thickness,and then cut into strips of convenient width, from which the blanks toform the eyelets are to be cut. The strips of metal so prepared may thenbe made into eyelets by any suitable machine; but inasmuch as thecomposition metal is less ductile than the metal usually employed, it isnecessary to make use in any machine i of a die and former which shallact to mould or suag'e the metal into the form of an eyelet rather thanto draw it out into that form.

The advantages which result from the use of this material in themanufacture of eyelet's are as follows: The metal being soft andyielding, does not dull the cutting edges of the punches anddies used toform the eyelet nearly as rapidly as in the case where a metal made fromcopper and its alloys is employed, and in case that an eyelet sticks inthe die, or a chip becomes lodged therein, the plastic character of themetal renders breakages less liable to occur. In addition to thisadvantage, all the necessity for annealing the eyelets is aroided, andthey are, as they come from the machine, perfectly ready forthe marketwithout being first electroplated.

i What I claim as my invention, and desire to secure by Letters Patent,is-

An eyelet made from metal composed of the elements and possessing thecharacteristics substantially as described.
